The fact that you said it is in "far northwestern MN" is a big plus to me. From your user name, I thought it might be in the twin cities area and had been subjected to a lot of road salt. The truck's location is very good news when it comes to rust, especially since has been sitting up there for so long. The rodent problem wouldn't bother me much since it is a truck (not a car) and will probably needs to be completely disassembled and everything stripped and refinished anyway. To me this is looking better all the time.
Where did you say it was ?
